Poppler is a PDF rendering library. Versions prior to 25.06.0 use `std::atomic_int` for reference counting. Because `std::atomic_int` is only 32 bits, it is possible to overflow the reference count and trigger a use-after-free. Version 25.06.0 patches the issue.

    Package        : poppler     Version        : 20.09.0-3.1+deb11u3 22.12.0-2+deb12u3     CVE ID         : CVE-2025-43718 CVE-2025-43903 CVE-2025-50420 CVE-2025-52885                      CVE-2025-52886 CVE-2026-10118     Debian Bug     : 1103545 1108784 1110463 1117046 1117853 1138708

    Multiple vulnerabilities were discovered in poppler, a PDF rendering     library, which could result in signature forgery, information     disclosure, denial of service, or potentially the execution of arbitrary     code.

    The following security issues have been identified (and fixed) in poppler     as shipped in Debian bullseye and Debian bookworm.

    CVE-2025-43903

        It was discovered signatures with non-empty encapsulated content         (typically adbe.pkcs7.sha1) were not correctly verified, thereby         allowing trivial signature forgery.

    CVE-2025-50420

        An infinite recursion issue was discovered in the pdfseparate(1)         utility, which may cause denial of service via crafted PDF input         file.

    CVE-2025-52886

        Kevin Backhouse discovered an integer overflow issue, which may lead         to use-after-free via crafted PDF input file.

    For Debian 12 bookworm, these problems have been fixed in version     22.12.0-2+deb12u3.

    In addition, the following issues have been fixed in the poppler version     as shipped in Debian bullseye (for bookworm, these issues were already     fixed in 22.12.0-2+deb12u2 from DSA-6334-1):

    CVE-2025-43718

        It was discovered that crafted PDF files containing deeply nested         structures within the metadata could lead to Denial of Service.

    CVE-2025-52885

        Antonio Morales discovered a use-after-free issue, which may lead to         arbitrary code execution via crafted PDF input files.

    CVE-2026-10118

        An integer overflow issue was discovered in tilingPatternFill, which         may lead to arbitrary code execution via crafted PDF input files.

    For Debian 11 bullseye, these problems have been fixed in version     20.09.0-3.1+deb11u3.

    We recommend that you upgrade your poppler packages.

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.04 host has packages installed that are affected by a vulnerability as referenced in the USN-7675-1 advisory.

    Kevin Backhouse discovered that poppler incorrectly handled documents with a large number of annotations.
    If a user or automated system were tricked into opening a specially crafted document, a remote attacker     could use this issue to cause poppler to consume resources, leading to a denial of service, or possibly     execute arbitrary code.
